Abstract
According to one aspect of the invention, an apparatus and process are provided for transporting sheet-shaped print material. A first transport element and a first contact element are actuated to transport a sheet-shaped print material with alignment against an alignment stop. A second transport element and a second contact element are actuated to transport sheet-shaped print material past the alignment stop without alignment against the alignment stop.
Description
- The invention relates to an apparatus for transporting sheet-shaped print materials.
- The majority of devices used in print processing and further processing require transporting paper or other sheet-shaped print materials through the device. In this process, the sheet-shaped print materials are aligned in different ways and manners, especially in the feeder area. Alignment of the sheet-shaped print materials is usually necessary in order to be able to carry out processing procedures in precise register, for instance, the printing of the sheet-shaped print materials with different colors, precisely-positioned folding or placement of holes in individual sheets.
- For lateral alignment of the sheet-shaped print materials, stops are frequently used, against which the sheet-shaped print material is guided. So, for example in folding machines, transport elements like inclined transport rollers or a diagonally running belt are used to guide the sheet-shaped print materials against a stop during further transport. In order to improve or allow for contact between the sheet-shaped print materials and the transport elements, contact elements are frequently assigned to the transport rollers to produce adequate contact pressure between sheet-shaped print materials and transport elements. For this purpose, ball rails, among other things, are used. These ball rails have recesses in which balls that can turn freely are placed. Plastic or metal balls can be used for this. The balls are selected such that they, with respect to their surface finish and weight, are optimally matched to the characteristics of the sheet-shaped print materials, e.g., base weight, surface finish, etc.
- In many applications, especially in copiers and/or digital printers, which typically have a number of different sheet formats in different supply bins, it is necessary to adapt the alignment of the sheet-shaped print materials to the format of the sheet-shaped print materials. Therefore, the stops are generally adjustable.
- In further print processing applications, usually a high degree of flexibility is necessary so that a further processing device often consists of a plurality of individual processing devices that are arranged one after the other and connected to each other. Often the term used for this is an “inline” configuration of the individual processing devices. During inline further processing, not all of the individual processing devices are always active in further processing of the printed product. However, changing the existing configuration can usually only be carried out with great effort. Therefore, it is desirable and/or necessary that the individual processing devices that are not involved are switched off or operate in bypass mode. In this case, the sheet-shaped print materials must be transported from one individual processing device to the next without any changes, especially without changes to their alignment.
- According to one aspect of the invention, an apparatus and process are provided for transporting sheet-shaped print material. A first transport element and a first contact element are actuated to transport a sheet-shaped print material with alignment against an alignment stop. A second transport element and a second contact element are actuated to transport sheet-shaped print material past the alignment stop without alignment against the alignment stop.
- FIG. 1 presents a schematic view of an embodiment of the apparatus according to one aspect of the present invention with the upper table swung up.
- FIG. 2 presents a schematic view of the underside of the lower table of the apparatus according to the present invention.
- FIG. 3 presents a schematic view of the apparatus according to the present invention with the upper table swung down.
- Various aspects of the invention are presented in FIGS.1-3, wherein like components in the numerous views are numbered alike. Generally known mechanical components, such as drive and/or guide elements implemented in carrying out the invention are shown schematically and/or are described in a general way, such components not being critical in the practice of the invention, and generally known in the mechanical arts in light of the description provided herein.
- Referring now specifically to FIG. 1, an
apparatus 20 comprises a lower table 201 and an upper table 202. Upper table 202 is mounted to the lower table 201 so that it can swing, ensuring the ability to pivot up and provide easy access to the space between the lower table 201 and the upper table 202. - Lower table201 is mounted on two
guide rods 242 that are fastened in the housing of theapparatus 20 on tworoller bearings 243. As FIG. 2 shows, on the underside of the housing of theapparatus 20 there is amotor 241 that drives abelt 24 by way of a transmission with the aid of which the lower table 201 can be moved precisely alongguide rod 242. At the same time as the movement of the lower table 201, the upper table 202 that is mounted so that it can swing also moves. - The lower table comprises a
first transport element 28 that is designed as a diagonally runningtransport belt 28, and twotransport elements 27 that are designed as three pairs oftransport rollers 27. Thetransport elements contact elements contact elements apparatus 20 in the direction of the arrow marked withreference number 4, is brought in contact withtransport elements transport elements Transport elements motor 271, mounted on the lower table 201, by way of abelt 272 and a transmission (not shown) of a type known in the art. - On the lower table201 there is also a
stop 23, against which thetransport element 28, in cooperation with thefirst contact element 22, guides a sheet-shaped print material. Since the lower table 201 can be moved laterally as described above, thestop 23 can also be moved laterally with respect to the transport path. - The
apparatus 20 is designed so that with the aid of the movable stop 23 a sheet-shaped print material having a width between 150 mm to 400 mm can be aligned centrally with respect to the transport path through theapparatus 20. - A control determines the position of
stop 23 depending on the format of the incoming sheet-shaped print material. For this purpose, the control receives instructions with regard to the format of the incoming sheet-shaped print material and the spacing of the center line of the sheet-shaped print material to the center line of the transport path planned for the sheet-shaped print material. The instructions can be transmitted to the control by upstream sensors of a type known in the art or retrieved from a memory of a type known in the art, in which information about the format of the sheet-shaped print material was previously stored. The control is of the type known for use in sheet handling machines. -
First contact elements 22 andsecond contact elements 26 are mounted in upper table 202. The first contact elements are designed asballs 22 that are mounted so that they can turn freely in aball rail 21. Plastic and/or metal balls are used for this purpose, which are coordinated in weight and surface finish to the sheet-shaped print materials being transported so that sheet-shaped print materials with a base weight of 50 g/m2 to 300 g/m2 can be guided againststop 23 in cooperation with thetransport element 28. - One example of a coupling mechanism between the
first contact element 22 and thesecond contact element 26 is presented in FIG. 3, on the upper side of the upper table 202. There is another motor 266 that drives adrive rod 263, that is mounted on the apparatus so that it can turn, by means of abelt drive 267. A firsteccentric element 264 and a secondeccentric element 265 are mounted ondrive rod 263. The firsteccentric element 264 is in contact withball rail 21 and is mounted on thedrive rod 263 in such a way that the rotation of thedrive rod 263 results in a lifting or lowering of theball rail 21. By lifting theball rail 21, thefirst contact elements 22 are also lifted and thus lose contact withfirst transport element 28. - The second
eccentric element 265 is in contact with a connectingrod 262 and is mounted ondrive rod 263 in such a way that the rotation ofdrive rod 263 causes a forward or backward movement of the connectingrod 262. The connectingrod 262 is in active connection, by way oflever 261, with thesecond contact elements 26 so that a forward or backward movement of connectingrod 262 causes a lifting or lower ofsecond contact elements 26. - The first
eccentric element 264 and secondeccentric element 265 are fastened to each other on thedrive rod 263 in such way that whenfirst contact elements 22 are lowered, thesecond contact elements 26 are lifted and vice versa, when thesecond contact elements 26 are lowered, thefirst contact elements 22 are lifted. In this way, at all times only thefirst contact elements 22 work together withfirst transport elements 28 orsecond contact elements 26 work together withsecond transport elements 27 in order to transport a sheet-shaped print material through theapparatus 20. Due to the position of thedrive rod 263 it is possible to determine whether an incoming sheet-shaped print material is transported through theapparatus 20 without any alignment. - In order to control the position of
drive rod 263, thedrive rod 263 is equipped with a marking 268 that turns along with the rod so that asensor 269 can monitor the position of thedrive rod 263. The marking 268 that turns along with the rod is implemented, e.g., using a perforated disk. - The apparatus described here for transporting sheet-shaped print materials is particularly useful for inline further processing of printed products from digital printing machines. Use in all copiers/printers in which sheet-shaped print materials are either optionally aligned or not aligned in bypass mode is also a possibility. Use in sheet-fed offset printing machines or further processing devices like folding, sealing or stapling devices is within the scope of the invention described here.
- As is evident from the description provided herein, a control and memory may be provided, with the aid of which the change between the first transport element and the second transport element occurs automatically according to an instruction stored in the memory means. The instruction can be inputted here by the operator when setting up the printing and/or further processing procedure, or by a control that determines with the aid of a sensor, whether an incoming sheet-shaped print material will be aligned or guided in bypass mode through the apparatus without alignment.
- The instruction can also be carried out by a mechanism that is mounted before the apparatus. This mechanism transfers the sheet-shaped print materials to the apparatus or the instruction is carried out by a central control unit that coordinates the entire printing and/or further processing procedure. In this way, operator intervention is not necessary when the apparatus is in operation.
- The first transport element may be a driven, diagonally running belt that guides the sheet-shaped print material laterally against a stop.
- The stop may be moved laterally. In this way, alignment can be adapted to different formats of the sheet-shaped print materials. The alignment of the sheet-shaped print materials is advantageously carried out with respect to the center line of the sheet-shaped print materials relative to the center line of the transport path or at specified distances from the center line of the transport path.
- Lateral adjustment of the stop may occur automatically, responsive to the control and memory, according to an instruction stored in the memory. The instruction can also be inputted here by the operator when setting up the printing and/or further processing procedure or be carried out by a control that determines, with the aid of sensors, which format the incoming sheet-shaped print material has and to what location the stop will have to be moved in order to achieve an appropriate alignment of the sheet-shaped print material. The instruction can also be carried out based on the format of the sheet-shaped print material and the corresponding position of the stop by a mechanism mounted before the apparatus that transfers the sheet-shaped print material to the apparatus. Also a central control unit that coordinates the entire printing and/or further processing procedure can carry out the instruction. In this way, operator intervention is not necessary for changing the stop and thus for format adjustment of the apparatus during operation.
- A motor-driven belt or a spindle or a cam plate may carry out the lateral displacement of the stop, as well as other suitable mechanisms.
- The second transport elements may be driven pairs of transport rollers and the second contact elements may be counterpressure rollers that are used to produce contact pressure between sheet-shaped print material and the second transport elements so that transport of the sheet-shaped print materials occurs without alignment.
- The first contact elements may be balls, whereby the balls are arranged so that they can turn freely in a ball rail and the balls as a result of their weight and surface finish produce contact pressure between sheet-shaped print material and the first transport element. Since the balls can turn freely around any axis, they do not make any marks on the sheet-shaped print material when it passes through the apparatus at an angle to the transport direction. The balls may be metal and/or plastic balls wherein it is possible to safely transport sheet-shaped print materials with a sheet weight of 50 g/m2 to 300 g/m2 and different materials like paper and transparencies.
- A coupling mechanism between a ball rail and second contact element may be provided that comprises a drive rod, which is fastened to the apparatus so that it can turn, as well as a first eccentric element in contact with the ball rail and a second eccentric element in contact with a connecting rod, whereby the first eccentric element and the second eccentric element are mounted on the drive rod; and a connecting rod and lever that produce an effective connection between the second eccentric element and the second contact elements.
- The apparatus may comprise a lower table and an upper table, whereby the coupling mechanism and the contact elements are mounted in the upper table located above the transport path of the sheet-shaped print materials and the upper table is attached to the lower table so that it can swing. Because of this, it is easy to open the transport path of the sheet-shaped print materials through the apparatus, for instance, to eliminate a paper jam.
- The apparatus may comprise a sensor and a marking, by means of which the functional position of the contact elements is monitored.
- Although the invention has been described and illustrated with reference to specific illustrative embodiments thereof, it is not intended that the invention be limited to those illustrative embodiments. Those skilled in the art will recognize that variations and modifications can be made without departing from the true scope and spirit of the invention as defined by the claims that follow. It is therefore intended to include within the invention all such variations and modifications as fall within the scope of the appended claims and equivalents thereof.
